Abstract: An auto-feed device and method for serially dispensing and applying plural reinforcement bar (rebar) fasteners features an elongate frame configured to carry plural rebar fasteners, the frame including a race for guiding the fasteners therealong; a feed mechanism coupled with the elongate frame for urging the fasteners toward a distal end of the frame; and a dispensing head adjacent a distal end of the frame, the frame and the dispensing head configured to serially dispense and apply the plural rebar fasteners at corresponding rebar junctions.

Abstract: A fastener for joining two pieces of rebar together in a rebar grid used to reinforce subsequently poured concrete is described. The fasteners include two clamp pieces that in certain embodiments completely wrap around a piece of rebar and are tightly secured thereto. Further, each clamp piece can swivel or rotate up to 360 degrees relative to the other clamp piece such that two rebar pieces intersecting at any angle can be coupled together.
